Bug ID: 54456
Summary: ChunkedInputFilter returning EOF when client closes
connection without sending end chunk
Product: Tomcat 7
Version: trunk
Hardware: PC
Status: NEW
Severity: normal
Priority: P2
Component: Catalina
Assignee: dev@tomcat.apache.org

Patch to fix the bug
In my case client is processing user's InputStream and then sending data in
chunks to server. At server end I read till EOF.
Client can be simple Java program or a web application.
I am facing issue when client gets error on user's InputStream and closes
connection with server. In that case ChunkedInputFilter is returning -1.
I have added logs and confirmed that endChunk is false.
Issue was fixed after I added following just before "return result;"
if (result == -1 && !endChunk)
throw new EOFException("Unexpected end of stream while reading
chunk body");
I think ChunkedInputFilter should return -1 only when it gets endChunk.
Also, from client end I am always sending complete chunk. So, in
ChunkedInputFilter I should get EOF from socket stream while reading next chunk
header (which is handled properly in ChunkedInputFilter) but that is not
happening.
I have attached patch. Patch was generated against tomcat/tc7.0.x/trunk
